It is given that Tyler’s math class found that it would take 2.5×10⁸ dollar bills to cover a square mile area. The surface area of the United States is about 3.8×10⁶ square miles.
The number of dollars will be calculated as below:-
A = [ ( 2.5×10⁸) x (3.8×10⁶) ]
A = ( 9.5 x 10¹⁴ ) dollars.
Therefore, the amount of dollars needed to cover the united states is 9.5×10¹⁴ dollars. The correct option is B.
